I just install update 7 from update 5. When I try to add a ldf/startup code under project option with existing projects from VisualDSP++ (e.g., dot_product_c) it shows some error message (see attached file). And after adding the LDF, you can't not remove it, and it did not seem to work. update 5 or update 6 works normally. My OS is windows XP, SP2. IE6.0.
